MATRIX-CONEHOLING MACHINE.

1 0H 213/ 1 0m it may concern Be it known that we, JOHN SELLERS BAN-ruor'r and Mixtfnrrz C. INDAHL, citizens of the lfnited States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvaniahave invented certain new and useful Improvements in MatriX-ConeholingMachines; and we do hereby declare the following to be a full, clear,and exact de scription of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thefigures and letters of reference marked thereon.

This invention relates primarily to the production of conical centeringcavities or seats in type matrices, such as those illustrated in PatentsNos. 625,998 of May 30, lean, and 725,653 of April 12, 1903, and has forits principal object the apid, economical and accurate formation of saidcentering cavities.

The invention is embodied in an automatic machine or mechanism whereinthe matrix blanks are taken one at a time, from a supply reservoir orgalley, delivered to and gaged tor position in a revoluble chuck, andthen presented or subjected to the action of one or more, preferablyit'our, automatically self-centering cutters operating to produce orfinish the conical centering ca vit v and locate the same in the axialcenter of the blank, after which the completed matrices are delivered insequence to a receiving receptacle or galley.

The invention consists in the novel constructions, arrangements andcombinations parts hereinafter tull v described, and inted out in theappended claims. in the accompanying drawings, illustratin; a preferredform of embodiment of the llH'UllIlUl'l FlQlll'Q 1 perspective view oian org; ized machine; 2 a top plan view R. is a front elevation; Fig. -2is a right end elevation: Fig. 5 is a rear elevation of a part. and 6 isa similar view oi the balance oi the machine, these last named figuresl'ieing taken on an enla re'ed scale. the line of junction beingindicattd b v a dotted pointing line on each figure.

Corresponding numerals designate like parts in the several figures.

Before entering upon a description of the automatic machine embodyingthe present in'iprovements, the nature of its product should be brieflyexplained in order that the extreme degree of accuracy required, and thedelicacy of the operation to be performed, may be the better understoodand appreciated.

The matrix herein referred to is a block of metal 1 (Fig. usually ofparallelepiped form, containing a type impression or matrix cavity 2 inone end and a conical seat 3 in the opposite end. In the type castingmachine a number of these matrices are associated together in a die caseor holder and subjected to the action of automatic shifting deviceswhereby any individual of the series is brought opposite the open end ofa mold, the latter adjusted to correspond with the selected matrix, anda conical pin is thereupon thrust into the conical seat or recess, tofirst center or adjust the matrix to final position, and then clamp andhold it upon the mold while the cast is being made. The centering pinoccupies a fixed position transversely of the mold and by its engagementwith the conical seat in the selected matrix determines the position ofthe character or head upon he body portion of the type, hence anydoparture from the predetermined. correlating positions of the centeringand matrix cavities will result in a corresponding displace ment of thecharacter resulting from the cast. To obtain. accurate registry betweenthe matrix and centering cavities two adjacent sides of each matrix areadopted and utilized as base lines or gages for elfecting the necessarymeasurements. and, in prac tice, the matrix cavity is first formed andjustified, 1'. (1., accurately positioned with relation to said baselines, before the centering cavity is completed. In some instances apreliminary centering cavity or cone hole is formed in the matrix at thetime the drive is made in the opposite end: but if so a subsequentjustifying or finishing operation is necessary, as so far it has beenfound ilUPlflCtlClllJlQ to produce a finished and accurately locatedcone hole by prcssure, owing to the irregular expansion of the metalwhen relieved from the great pressure required for displacement, and thetendency of the punch to drift slightly to one side or the other of theaxis. To insure the proper seating of the conical centering pin in thematrix it is the practice to make the seating cavity in the form of thefrustum of a cone bv forming a shallow drill hole or cavity l: at theapex of the conical surface. as illustrated in Fig. 4-6.

The present machine is designed to re ceive and operate upon matrices(hereinafter referred to as blanks after the matrix recess has beenapplied, and whether or not the blank is provided with the preliminarycone hole referred to.

For convenience of description the machine as a whole. may be dividedinto two components, to-wit; the pcrating members or those actingdirectly upon the article or blank. to change its shape or maintain orvary its position; and the actuating mechanism for conveying motion tothe operat .ing members and uniting the latter into an organizedautomatic machine. Said operating members include the chuck and itsspindle, together with means for gaging the position of the blank, forclamping and rotating the latter. and for arresting the LOO
